[QUOTE="JonB, post: 30742, member: 3047"] Setting up your camera for a custom white balance is fairly easy and its necessary if you want accurate color. Every light source has a different color temperature. On your camera there are basic settings for AWB Average White Balance, Tungsten, Florescent, Sunlight and so on. There is also a "Custom" setting. There are a couple ways to get a custom white balance - several more maybe - but I'll address two. 1) an Expodisc is a type of filter you hold in front of your lens and aim at the dominant light source and take a pict. Then you tell your camera to use that as the white balance image. Your camera will automatically set the white balance for all shots from then on. Every time the light changes - you have to take a new image and reset the white balance. 2) instead of popping for a $130.00 72mm filter - you can use the Chuck Gardner method of setting a custom white balance. Chuck recommends using an 18% gray card - I use a white one. The camera only really sees in black and white and does all kinds of gymnastics to get color out of the file. It actually tries to level everything to a middle gray - so a white card will work almost as easily as a gray one. So - get a nice clean white wash cloth and keep it in your bag.
